Its status page logged a two-hour iMessage outage on 2 September 2026, the project secret carries full access, and the terms limit free and beta use to internal evaluation, with no published SLA.\n\n**Vonage Messages API + MCP.** POST /v1/messages covers six channels, with SMS failover for WhatsApp and RCS. No idempotency key, and channel rejections arrive only by status webhook after a 202.\n\n## Before you call either\n\n### Photon\n\n1. Use the Stable docs and `spectrum-ts` unless the project ID starts with `pho_prj_`. Stable and Beta packages, hosts and credentials don't mix\n2. Design flows so the person texts first. Photon ties line flags to cold outreach, bursts and more than two or three follow-ups\n3. Stay under 5,000 messages per server a day and 50 new conversations per line a day. Further sends are rejected until the window resets\n4. Give each outbound message a stable `clientGuid` so a retried job doesn't send it twice\n5. Dedupe webhooks on `X-Spectrum-Webhook-Id` plus the event's own id, answer within 30 seconds, and reconcile, because events are dropped after six attempts\n6. Keep the project secret out of the agent's context. It grants full management access and doesn't expire\n\n### Vonage Messages API + MCP\n\n1. Keep api.nexmo.com as the host, don't rewrite it to vonage.com\n2. Use the Messages API, not the legacy SMS API\n3. Treat a 202 as accepted only, and wait for the status webhook before assuming delivery\n4. Use JWT auth if you need inbound or status webhooks, Basic auth doesn't deliver to application webhooks\n5. Verify the webhook JWT and its payload_hash against the raw body\n\n## Questions\n\n### Which is better for AI agents, Photon or Vonage Messages API + MCP?\n\nVonage Messages API + MCP scores 66.8 (B) on agent readiness against Photon's 53.5 (D), and leads in 5 of 7 scored categories. Photon leads on agent ergonomics and transparency \u0026 trust.\n\n### Can an agent call Photon and Vonage Messages API + MCP without installing anything?\n\nYes.
